3 Claims.

This invention relates to a machine for operating on sheet material while the latter is being fed to and through the machine, lmore particularly to the mounting of the operating elements on each shaft. In machines of this type, the operating elements, suchas slitters or shaping rolls, must be adjusted longitudinally of and fixed to the shaft on which they are mounted, so as to register or co-act with a related element on the other shaft'. Heretofore, so far as I am aware, such adjustments have been made by means of a micrometer or by a cut and try method, after'the slitters or rolls were placed on the shaft, so that much labor and time was required to set the elements in proper position; and when it became necessary vto change the settings of these elements. the same adjustment operations were again required.

One object of the invention'is to provide an improved machine of this type wherein a plurality of operating elements may be secured together in an assembledrelation as a unit and such unit assembled on a shaft of the machine and removed therefrom at will, this arrangement permitting the adjustments to be made by the use of a gage before the elements are placed on their lsupporting and driving shaft or by the use of spacers having predetermined widths.

Another object of the invention is to provide an improved machine of this type in which provisionV is made to support a plurality of operating elements inrigid relation on a member which is removably mounted on and in driving connection with a shaft and to permit ready removal of the member, whereby the machine may be changed to meet various conditions in an easy manner and without undue loss of time.

Other objects of the invention will be apparent to those skilled in the art to which myinvention relates from the following description taken in connection with the accompanying drawin'gs, wherein Fig. 1 is a fragmentary side elevation of a machine embodying my invention, parts being in section or broken away.

Fig. 1a is a fragmentary section of the line Ia-Ia of Fig. 1. I

Fig. 2 is a 'section on the line 2 2 of Fig. l.

Fig. 3 is a longitudinal section of an assembly carrying a plurality of slitters or cutters.

Fig. 4 is an elevation of an assembly showing a plurality of slitters or cutters.

Fig. 5 is a view showing a modification.

In the drawings, I indicates a support on which are mounted spaced standards 2, 3. The standard 2 is shaped to` mount suitable anti-friction bearings 4 for` one end of a shaft 5 and an adjustable bearing box 6' for thetcorrespo'nding en'l of a shaft 1. The standard 3 is shaped to mount spaced bearings 8, 8a, for the'other end of the shaft l and spaced bearing boxes 9, 9a, for the other end of the shaft 1, the standard 3 forming a housing Il for a suitable driving mechanism for driving the shafts i, I, connected to and driven by a shaft I'I from a motor (not shown). The standards 2, 2, are provided with yguides I2 (see Fig. l), in which the boxes 6, 9, 9a, may be raised and lo'wered for a purpose later set forth, as well a-s to adjust the shaft 1 relative to the shaft 5 to co-actively relate the operating elements on one shaft to those on the other shaft.

For this purpose, a. screw I3 is rotatably connected at lts lower end to each box 6, 9, 9a, and its upper end is threaded through a nut I3a xedly mounted in a bridge wall I3'. The upper end of each screw I3 is provided with a worm gear Ibfin mesh .with a worm `I3c Leach worm and the adjacent worm gear being mounted in a casing Il) fixed to a. shaft I5, so that by rotating the shaft, as by means of a hand wheel I6, the screws I2 may be simultaneously operated to raise or lower the boxes .6, 9 and 9a, whereby the shaft -1 is raised or lowered. 'I'he casing's I 4 are mounted on bridge walls I3' suitably secured to the'standards 2, 3'. The standard 2 is adjustably mounted on the support I, whereby it may be moved in a direction endwise of the shafts` i, l, away from the standard 3 for a purpose later set forth. For this purpose,'the standard 2 is provided with a shoe 2a which engages ways Ia on the support I. The shoe is provided with a depending lug 2b, having a threaded opening to form a nut for a screw I8. The screw I8 is rotatably mounted at its opposite ends in bearings I9, I9a, provided on the support I and held against endwise movement by aV collar 2| engaging the outer wall of the bearing I9 and a cap 20a fixed thereto. Rotation of the screw will operate to slidevthe standard 2 in either direction.

To permit of the adjustment -or movement of the standard 2, as above vdescribedand to permit of ready assembly of the shaft I5, the latter is made in sections the adjoining ends of which are connected together by slip-over collars I5a each of which is secured to the adjacent sections by set screws lib.

2I indicates a sleeve slidably fitting each shaft 5, 1, and keyed thereto by a key 22. The inner end of each sleeve 2I, when mounted on its'shaft, engages an annulus 23 provided on the inner end portion of the adjacent shaft and its outer end is engaged bya`nut 24 removably threaded on the opposite end portionA of the adjacent shaft and arranged to clamp the sleeve -2I between it and the annulus 23. Each sleeve 2| is provided at its inner end with an outwardly extending annular flange or wallf 2Ia, forining an abutment, and between this wall and a nut .25, threaded on the outer end portion of the sleeve,

I mount a plurality of operating elements 26' spaced from each other by collars' 2l and clamp the elements and collars together by the nut 25.

The operating elements, as well as the spacingA collars 2lV by preference, on each sleeve 2| are keyed thereto, so as to be driven by the adjacent shaft. The elements 26 and spacers 2l are in the form of construction shown for illustrative purposes, slid onto the sleeve at that end opposite to the abutment Zia. collar 2l between each element 26 and the adjoining element 26, but in place of one collar I may use two or more thereof; in either event, the collars 2l may be of a predetermined width so that when the collars 2l and operating elements are assembled on a sleeve 2 i, the operating elements will have a predetermined spaced relation and will thus` be in position to co-act with the predetermined spaced elements on the other sleeve when both sleeves are mounted on the shafts 5, T. Accordingly, the operating elements and spacers may be mounted on each sleeve 2| with the elements spaced in their predetermined operating position before the sleeve is positioned on its shaft. Thisarrangement permits more than one sleeve 2l for each shaftwith operating elements 26 assembled thereon in varying predetermined relations, to be provided ready for,

use to meet different conditions, so that it only becomes necessary to remove they sleevesV 2i from the shafts 5, l, and insert thereon sleeves 2i having elements set in the desired spaced relation'.l In this connection it will be noted that the operating elements and spacers, when assembled on a sleeve, are clamped thereto in rigid relation and may be handled as a unitary structure.

To mount the sleeves and elements thereon on the shafts 5, I, first, the hand wheel I6 is operated to rotate the shaft l5, which in turn through the screws I 3 and bearing boxes 6, 9,

dit

Qa, will raise the shaft 1 to disengage the operating elements thereon from the operating elements on the shaft 5; next the slip-over collar Mia between the standards 2, 3, will be disconnected from one ofthe adjacent shaft sections; next the standard 2, bearings tand box 6 are moved outwardly on the support l and then the nuts 2d are removed from the shafts 5, l, which will leave the latter supported in their bearings, d, 8a and boxes Q, 9a. Sleeves 2i with elements 2E assembled thereon are then mounted on the shafts and clamped thereto by the nuts 26. The standard 2 is then moved back into its normal position, the sections of the shaft i5 connected and the bearing boxes E, 9, sa, lowered to position the elements 2 on the sleeves in co-active relation. To remove the sleeves. 2i and substitute others therefor, these operations are repeated.

In Figs. 1 and 3 I have shown sleeves having four slitting elements 2t mounted thereon arranged to slit sheet material A into three strips and trim off the opposite marginal edges thereof, whereas in Fig. 4 I have shown a sleeve 2i havingmounted thereon three slitting elements 26a, which in connection with complementary related slitting elements are adapted to slit sheet material into two strips and trim od the opposite marginal edges thereof. Fig, '5 illustrates a modification wherein the operating elements consist of shaping rolls 253: on a sleeve Zlzt spaced thereon by collars 2in: and. keyed to the sleeve as already described. The shaping rolls 26a: may be employed for shaping sheet metal during feed- I have shown one andere me thereof. It, wm be evident that shaping It will be understood that the sheet' material y may be fed to the operating elements in any suitable manner.

To those skilled in the art to which my invention relates many changes in construction and Widely diering embodiments and applications of the invention will suggest themselves without departing from the spirit and scope of the invention. My disclosures and the description herein are purely illustrative and not intended to be in any sense limiting.
